An ingenious encounter between paper and pen. This is a flat-bound notebook from the PERPANEP series. A perfect-bound double-page binding that eliminates unevenness when opened. Uses original, ultra-smooth paper that allows the pen to glide with a light touch, as if in zero gravity. Eliminating as much of the stubbornness that can interfere with thought, you can write smooth curves and uninterrupted straight lines with a light touch, without applying pressure. Ink shades are clearly visible, allowing you to enjoy the texture of letters and lines. (Because the paper surface is so smooth, lines written with a pencil or mechanical pencil tend to be faint.) 4mm grid lines make it easy to write letters and diagrams in a balanced manner. **Reseller Disclaimer: Kokuyo items cannot be sold on Amazon, eBay, or Walmart.com.**
